It is also used to reduce the weight of the vehicle so it can reduce the energy consumption. Most researches focus on uniaxial loading whereas, in practice, biaxial loading is likely to occur. Researches also show that a multi-cell column performs better in crashworthiness compared to conventional or single-cell column. This research aims to conduct numerical simulations of the multi-cell thin-walled column subjected to biaxial loadings. Numerical simulations have been done to five different cross-section aluminium square columns: single-cell (V0H0); multi-cell with one vertical plate (V1H0); multi-cell with two vertical plates (V2H0); multi-cell with one vertical and one horizontal plates (V1H1); and multi-cell with two vertical and one horizontal plates (V2H1). V2H1 column performs high specific energy absorption when it is subjected to fully axial and axial-dominant loadings. It absorbs up to 69.07% more than single-cell column does. On the other hand, V2H0 column performs high specific energy absorption when it is subjected to fully bending and bending-dominant loadings. It absorbs up to 99.56% more than single-cell column does.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Biaxial loading,Energy absorbers,Horizontal plates,Multicell,Specific energy absorption,Square columns,Thin walled column,Uni-axial loading[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]biaxial loading,crashworthiness,energy absorber,multi-cell,thin-walled structure[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]ACKNOWLEDGMENT This research was conducted in and supported by Laboratory of Lightweight Structure, Faculty of Mechanical and Aerospace Engineering, Institut Teknologi Bandung.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/ICEVT48285.2019.8993994[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
